The hierarchical arrangement of this phylogeny provides a
comparative and predictive framework for all fundamental and applied
biology. Our understanding of the Tree of Life has advanced rapidly
over the past decade fuelled by enormous progress in the fields of
genomics and information technology.
Although well studied, the evolutionary
relationships among major avian groups are contentious.The very
nature of the evolutionary history of organisms and the limitations
of current phylogenetic reconstruction methods mean that parts of the
tree of life might prove difficult, if not impossible, to resolve
with confidence.Phylogenomics is useful for resolving difficult
phylogenies and for verifying or overturning relationships created on
the basis of single genes.
phylogenomics analysis of birds, the genomes presented here were sequenced, de
novo assembled and annotated for functional elements. These genomes will
be helpful to construct the evolutionary history of birds, which has
the potential to provide answers to several outstanding fundamental evolutionary
